Zeeb <[email protected]> CommitDate: 2026-06-05 12:09:22 +0000 LinuxKPI: 802.11: add note about rate control support under boot -v We currently do not support rate control in LinuxKPI. As more drivers and chipsets gain suppport for higher throughput add a note under bootverbose if we hit one of these cases (currently only older iwlwifi chipsets).
